3 Claims. Cl. 169-26) This invention relates to fire extinguishersparticularly adapted for individual use, such as in the home, in a motorvehicle, boat or airplane, and in particular a cap having a fusible orreadily breakable element incorporated therein with the cap adapted tobe crimped over the bulge on the neck of a bottle and with the elementadapted to release a closure on the neck of the bottle when fused orbroken.

The purpose of this invention is to provide means for forming a fireextinguisher with a conventional container, such as a bottle and inwhich the same container may be refilled and reused by crimping a newcap thereon.

Conventional types of fire extinguishers are comparatively costly andfor this reason they are very seldom used in motor vehicles, residences,small boats and the like. With this thought in mind this inventioncontemplates a method of forming a fire extinguisher whereby a bottlecontaining fire extinguisher fluid may be sealed with a cap having anelement therein that is readily fused or broken to release the cap.

The object of this invention is, therefore, to provide a cap adapted tobe mounted on the neck of a bottle or the like whereby with the bottlefilled with a fire extinguishing fluid the fluid may be sealed in thebottle and released only upon fusing of an element or upon manuallybreaking the element.

Another object of the invention is to provide a cap for sealing a bottlecontaining fire extinguishing fluid in which the cap is adapted to beused on bottles now in use.

A further object of the invention is to provide a fire extinguisherformed with a sealing cap on a conventional bottle in which the bottleis adapted to be covered with plastic or the like to change theappearance thereof.

A still further object of the invention is to provide a fireextinguisher which is of a simple and economical construction.

With these and other objects and advantages in view the inventionembodies a fire extinguisher cap including a tubular casing, preferablyof copper, and adapted to be crimped over a bulge on the outer surfaceof a neck of a bottle, a disc having an annular flange freely positionedagainst the end of the neck of the bottle providing a closure and a discfreely hinged in the end of the outer casing and adapted to be securedin position with a fusible element and wherein upon fusing or breakingof said element the disc providing the closure is released to releasefluid in the bottle.

Other features and advantages of the invention will appear from thefollowing description taken in connection with the drawing, wherein:

Figure 1 is a side elevational view showing the improved fireextinguisher with the lower portion of a cap on the end of a neck of thecontainer of the extinguisher broken away showing the disc for releasingthe closure of the container in the sealing position in full lines and1n the released position in broken lines.

Figure 2 is a vertical section through the fire extinguisher taken online 2-2 of Fig. l.

Figure 3 is a view looking upwardly toward the lower end of the fireextinguisher.

Figure 4 is a plan view of the fire extinguisher.

Figure 5 is a detail illustrating the cap of the fire extinguisherlooking toward the side thereof on which the disc is hinged andshowing aportion of the neck of a bottle in broken lines.

Figure 6 is a detail illustrating the flanged closure member of theextinguisher.

Figure 7 is a detail illustrating the releasing disc by which theclosure member is retained in position on the end of the neck of thebottle.

Referring now to the drawing wherein like reference characters denotecorresponding parts the improved fire extinguisher cap of this inventionincludes a sleeve 10 having an opening 11 in one side and adapted to bepositioned over a bulge 12 on a neck 13 of a bottle 14 with the upperedge of the sleeve crimped over the bulge 12, as indicated at the point15 and, as shown in Figs. 1 and 2 a closure 16 is retained in sealingrelation with the end of the neck of the bottle with a disc 17, a prong18 of which extends through the opening 11 of the sleeve and a flange 19of which, that is positioned on the opposite side, is secured to theedge of the sleeve 10 with a fusible element 20, such as woods-solder ormetal.

The closure E6 is provided with a web 21 and an annular flange 22 andthis member is retained in position, as shown in Fi 2 by the disc 15that is hinged in the opening 11 with a prong 1S and as the fusibleelement 2% is fused or broken the disc 17 drops downwardly as indicatedby the broken lines in Fig. l with the prong 13 dropping from theopening 11 whereby the closure 16 is released so that it drops from theneck of the bottle and with the closure in removed fire extinguishingfluid, as indicated by the numeral 23 may be used from the bottle in theconventional manner.

In the design shown the bottle is provided with a hanger formed with anannular band 24 with arms 25 and 26 extended upwardly over the upper endof the bottle. The upper ends of the arms are provided with flanges 27and 28, respectively and a hook, nail, or other fastener as indicated bythe numeral 29 may be placed through openings in the flanges to supportthe fire extinguisher.

The arms 25' and 26 are provided with bulging sections 39 and 31,respectively and openings with tapering upper ends, such as keyholeslots are provided in the bulging sections as indicated by the numeral32. By this means the fire extinguisher may be placed over the head of anail or other fastener.

Also, as illustrated in Fig. 2 the bottle or container may be coveredwith a layer of plastic, as indicated by the numeral 33 to change thecolor of the container or improve the appearance thereof.

Although it is preferred to use an element, such as the element 2t),that will fuse at a temperature of degrees B, it will be understood thatother suitable fusible materials may be used and materials may beprovided to fuse at different temperatures.

It will be understood that modifications, within the scope of theappended claims, may be made in the design and arrangement of the partswithout departing from the spirit of the invention.

What is claimed is:

l. A fire extinguisher cap comprising a closure including a web havingan annular flange and adapted to be positioned on the end of a neck of abottle, a sleeve positioned around said closure and adapted to becrimped on the neck of the bottle, a disc hinged in the lower end ofsaid sleeve, and a fusible element connecting the sides of the discopposite to the side on which the hinge is positioned for retaining thedisc in the sleeve with the disc adapted to retain the closure againstthe end of the neck of a bottle upon which the sleeve is crimped.

2. A fire extinguisher comprising a bottle having a neck with an annularbulging section spaced from the end thereof, a sleeve having an openingin 7 one side thereof positioned over the neck of the bottle and crimpedover the annular bulging section thereof, a closure having a web with anannular flange thereon positioned over the end of the neck of the bottleand surrounded by said sleeve, a disc having a prong extended throughthe opening in the sleeve and positioned against the closure on the endof the bottle, a fusible element temporarily connecting the disc to thesleeve at a point opposite to that from which the prong extends, and ahanger positioned on the upper end of the bottle.

3. A fire extinguisher comprising a bottle having a neck with an annularbulging section spaced from the end thereof, a sleeve having an openingin one side positioned over theneck of the bottle and crimped over theannular bulging section thereof, a closure having a web with an annularflange thereon positioned over the end of the neck of the bottle andsurrounded by said sleeve, a disc having a prong extended through theopening in the sleeve and positioned against the closure on the end ofthe bottle, a fusible element temporarily connecting the disc to thesleeve at a point opposite to that from which the prong extends, acoating covering the outer surface of the bottle, and a hanger on thebottle.
